The LMX2492RTWT is low noise 14GHz wideband Delta-sigma Fractional N PLL with ramp and chirp generation. It consists of a phase frequency detector, programmable charge pump and high frequency input for the external VCO. The LMX2492 supports a broad and flexible class of ramping capabilities, including FSK, PSK and configurable piecewise linear FM modulation profiles of up to 8 segments. It supports fine PLL resolution and fast ramp with up to a 200MHz phase detector rate. The LMX2492 allows any of its registers to be read back. The LMX2492 can operate with a single 3.3V supply. Moreover, supporting up to 5.25V charge pump can eliminate the need of external amplifier, leading to a simpler solution with improved phase noise performance.
